Kind words from clients
Thank you all!
"My team at EdTrust-West had the immense pleasure of working with Sarah on reimagining our Staff Onboarding Program. Sarah designed a strategic, multi-month onboarding experience that has already resulted in staff feeling supported and clear on their roles at our organization. We are now well-positioned to execute a consistent onboarding program moving forward. I was blown away with by Sarah's high level of organization, HR insight, and efficiency for such a complex, multi-month project. I look forward to hopefully partnering with Sarah again in the future!"
Natalie Johal
Associate Director, People & Operations
"Sarah has been an outstanding thought partner throughout this process: rigorous and focused on work plan/project management, curious and adaptable to our org idiosyncrasies, and exceptionally nuanced in helping us think through various values trade-offs. Truly a pleasure to work with Sarah and hope we'll have a chance to do so again."
Aaron Dorfman
Executive Director
"Sarah has a gift for simplifying what could otherwise be complex problems, and for creatively solving those problems. She streamlined our HR processes and helped us identify and solve issues we had not even seen. She was a joy to work with. I would recommend her to anyone."
David Snyder
Executive Director
"Sarah Chostner was a pleasure to work with! She was very professional but personable which made the work fun and light considering how busy our organization gets! She helped our organization get very clear on where we needed to improve and the opportunities we had by simply leaning more into the feedback from our team members. Her people-centered approach helped us revive a disengaged team! I would highly recommend working with Sarah, her experience and work ethic are excellent and needed in this ever changing climate in non profit work. "

Menne Hall
Chief Program Officer
"Sarah did excellent work for our organization leading us to a new and improved performance management process grounded in a new competency model. She's a phenomenal listener with a strong ability to translate open-ended conversations into specific revisions. She brings strong content knowledge to the table, is a great communicator, and quickly learns the needs of a new client. Would strongly recommend for all your Talent/HR needs!"
Rick Zadd
Vice President of Finance and Operations
"Working with Sarah / Aprium Advisors was a game changer for my organization. We are a small non-profit without dedicated HR assistance and limited capacity. The essential policies and practices that non-profits like ours need in place to grow took years for us to develop on our own. Sarah helped us develop employee onboarding and handbook materials and a multi-year HR strategy in a matter of months. It's rare to find an HR professional who is so knowledgeable, technically savvy and enjoys the work they do. Sarah is all of these things and more. With the tools Sarah helped us develop, I am a more confident Executive Director and even more excited about my organization's growth. I cannot recommend Sarah and Aprium Advisors highly enough. Thank you!"
Rachel Johnson-Farias, Esq.
Founding Executive Director
"Sarah is an exceptional professional! She helped us with a full HR audit, created an employee handbook from scratch, and conducting a salary study. For all three projects, she communicated regularly and effectively and kept all of the pieces organized and easy to access. She was incredibly patient with all of our questions and has a beautiful way of balance individuals' suggestions and points of view with the needs of an organization. She also built buy-in and trust with our staff as part of all of these processes. Sarah has set us up for success and provided us tools that can grow with us. She is, by far, one of the best professionals I have ever had the pleasure of working with. You will be in credibly good and capable hands with her!"
Bella Ben-Shach
Senior Director of Operations
"I had the pleasure of working with Sarah on crafting our company's employee handbook as well as employee pathways and job descriptions, and I couldn't be more impressed with the results. She demonstrated a profound understanding of HR policies and best practices, guiding us through the entire process with expertise and professionalism.
Sarah possesses an exceptional ability to translate complex legal jargon into clear and concise language that resonates with employees at all levels. Her attention to detail ensured that our handbook not only complied with regulations but also reflected the unique culture and values of our organization.
Moreover, Sarah was always responsive, proactive, and collaborative throughout the project, making the entire experience seamless and enjoyable. I highly recommend her & Aprium Advisors to any organization seeking expert HR consultation and support."
Brittany Alvarez
Executive Director
"Working with Sarah was an absolute pleasure. She is highly organized, incredibly knowledgeable, and easy to collaborate with. Her guidance not only helped us meet our goals but also uncovered important blind spots we hadn’t considered. I would confidently recommend and hire her again in a heartbeat."
Zima Creason
Executive Director
"We partnered with Sarah to guide us through a period of intensive capacity building and restructuring within our organization. As a result of our partnership we successfully hired our first in-house Talent/HR leader. Sarah helped us from start to finish, crafting the job description, creating a rigorous interview process, and developing a robust onboarding plan. Additionally, she was an invaluable thought partner regarding change management, and co-created a meaningful staff engagement plan with us. She centered racial equity in every step of the process. I would jump at the chance to partner with Sarah again!"
Emily Bell
Director
"What truly sets Sarah apart was her thoughtful engagement throughout the entire process. She didn't simply review or draft policies; she engaged with us in a collaborative manner, co-creating solutions that were practical, values-aligned, and reflective about the impacts for our organization and staff. The result is a revised handbook that not only provides clear and effective guidelines, but also embodies our organization's ethos and fosters a culture of care.
I wholeheartedly recommend Aprium Advisors to any organization seeking to enhance their HR policies with expertise, empathy, and a deep understanding of organizational values. The exceptional service has made a significant positive impact on our team, and we are incredibly grateful for Sarah's partnership. "

Ami D.
Director of Organizational Culture and Development
"We had the pleasure of working with Sarah over the course of the year on a training series focused on supervisor development. From the initial consultation through final delivery, her professionalism, subject matter expertise, and commitment to excellence were consistently evident. She took the time to thoroughly understand our organizational goals, workforce dynamics, and training needs. The customized training modules she developed were practical, engaging, and aligned with our operational priorities. Feedback from our supervisors was overwhelmingly positive. The tools created and shared will support the team moving forward. One of the standout qualities of Sarah was her ability to blend strategic insights with real-world application. The sessions were not only informative but also interactive, fostering open discussion and active participation. We highly recommend her to any organization seeking a knowledgeable, reliable, and results-oriented partner in leadership development."

Katherine Behrens
Chief Administrative Officer
"I am writing my first input reviews of the year using the new performance review system, and WOW! It is infinitely superior to write reviews this way. Before, I was often spending way too much time spinning my wheels during review writing. I know I was a part of this effort, but I feel very much like a happy customer right now! Being able to hone in on the most salient bullets in the performance standards for each person, copy those into the review, and then elaborate on why those are most important- it feels magical.

Maeve Bowen
Senior Director, Human Resources
"Aprium Advisors was an incredible resource for our community-based network of early childhood centers. Sarah provided thorough research, thoughtful recommendations and helped us move important work forward related to talent management. As a small nonprofit, we benefited from having access to the expertise and reliability that Aprium provided. I would highly recommend Aprium and look forward to continuing to benefit from Sarah’s intentional approach. "

Kelli Pfaff
Executive Director
"Aprium Advisors is an incredible asset for our organization. From Sarah's positive and collaborative problem solving to the strong technical skills and resources, her expertise is strengthening our system in a values-aligned and equity-focused manner. It has been a true joy to work with Aprium Advisors and I highly recommend you do so as well."

Lizzie Choi
Chief Operating Officer
"I highly recommend working with Sarah! We had an executive transition that Sarah helped smooth out. She was excellent at sharing frameworks and creating alignment with stakeholders across the org. She quickly built trust with many individuals and helped us deepen our understanding of each other and the organization's goals at large. I highly recommend her for other organizations navigating leadership transitions or seeking a more inclusive leadership model."

Adrian Tirtanadi
Executive Director
"Sarah Chostner of Aprium Advisors is wonderful with which to work. Her knowledge and expertise is invaluable to CEOs looking to get expert compensation studies, bespoke HR solutions, problem solving and partnership for organizational development. Sarah delivers on commitments, works ahead of deadlines and provides a thoughtful and strategic counsel role that is invaluable to CEOs. I highly recommend Sarah to nonprofit and association clients."

Debbie Mason
Interim CEO
"Sarah Chostner is the perfect partner for organizations navigating transformative strategic planning and executive leadership growth. At Jeremiah Program, Sarah helped us truly “turn the corner” in how we approach the CEO 360 review. She guided our CEO 360 review process from end to end, thoughtful tool design all the way through executive compensation recommendation discussions with our Board.
I've worked with many consultants and have consulting experience myself; what sets Sarah apart is in a very short span of time Sarah showed her ability to represent our people strategy and organizational context in Executive and Board spaces where I was not present. I had complete confidence that she understood our organization well enough to advocate thoughtfully, ask the right questions, and move conversations forward in a way that built trust and clarity. This is something you want in a consultant, to take the work off your plate!
For organizations wanting to ensure their CEO evaluation, CEO compensation recommendations, and leadership accountability practices evolve alongside organizational growth, Sarah is exactly the kind of consultant you want by your side."
